摘要： A hot water delivery system includes a water heater, a mixing valve that is coupled to the output of the water heater, and a plurality of loads that are coupled to the output of the mixing valve. A load set point temperature of each load that is representative of a maximum temperature of the hot water that is to be delivered to the respective load is set by a user. Responsive to detecting the occurrence of an event associated with a load of the plurality of loads, a controller of the water heater controls the mixing valve to adjust the temperature of the hot water from the water heater to the load set point temperature associated with the load, provided the load set point temperature of the load is different from a water heater set point temperature at which the water heater maintains the hot water therein.

摘要： A method of operating a tankless water heater for heating a continuous supply of water. The method includes detecting a water flow condition within a heating chamber of the tankless water heater and regulating electrical current to first and second heating elements in response thereto. Both the first and second heating elements are located in the heating chamber, and respectively have first and second wattages, where second wattage is different than the first wattage. The regulating step further includes providing electrical current to the first heating element and not to the second heating element when a first flow condition is detected, and providing electrical current to the second heating element and not the first heating element when a second flow condition is detected, and providing electrical current to both of the heating elements when a third flow condition is detected.

摘要： In a hot water supply apparatus including a heat exchanger to which water heated by renewable energy or waste heat from other heat sources is supplied, a controller performs an intermittent combustion control in which combustion and combustion stoppage in a burner are repeated as a condition in which a water supply temperature exceeds a predetermined upper limit of the water supply temperature. In the intermittent combustion control, a combustion fan is caused to operate during the combustion and to at least temporarily, preferably always, operate during the combustion stoppage.

摘要： Embodiments of the disclosure are directed towards systems and methods for regulating a water heater via a thermostat. The thermostat comprises a receiver configured to receive one or more inputs from one or more sensors configured to monitor, for a predefined duration of time, usage pattern of the water heater. Further, the thermostat comprises a controller configured to determine, via a machine learning neural network, a scheduling pattern for hot water based on the monitored usage pattern. The controller is further configured to operate the water heater based on the scheduling pattern.
